【摘要】：为能够对既有公路的排水系统进行全面准确地评价,通过对公路排水状况影响因素的分析,建立了一套公路排水状况的评价指标体系。采用模糊综合评价法,在专家打分阶段不同于以往的具体打分而采取给出打分区间的方法,运用蒙特卡洛模拟产生符合给定区间的一组随机得分,再结合层次分析法与熵权法确定的影响道路排水系统的因子的综合权重,进行排水系统的模糊综合评价。在此基础上,迭代多次汇总各次模糊评价结果,并将评价结果与现场实测进行对比。结果说明:该评价体系具有一定的科学性,可为公路排水系统的养护工作提供一定的参考。
[Abstract]:In order to evaluate the drainage system of the existing highway comprehensively and accurately, a set of evaluation index system of the drainage condition of highway is established by analyzing the influencing factors of the drainage condition of the highway. The fuzzy comprehensive evaluation method is adopted to give the scoring interval in the expert scoring stage which is different from the previous concrete scoring method. Monte Carlo simulation is used to produce a set of random scores in accordance with the given interval. The fuzzy comprehensive evaluation of drainage system is carried out by combining the comprehensive weight of factors affecting road drainage system determined by analytic hierarchy process (AHP) and entropy weight method. On this basis, the fuzzy evaluation results are summarized several times, and the evaluation results are compared with the field measurements. The results show that the evaluation system is scientific and can provide some reference for the maintenance of highway drainage system.
